How to display image from iMac to TV?

Question

HDMI

Using a thunderbolt adapter and an HDMI cable, I connected the monoblock to the TV. I turn it on: nothing is displayed on the telly, TV is not displayed in the computer settings. In System Preferences -> Monitors there are no connected devices.

Answer 1

If you connect using HDMI, you need to switch the interface on the TV to which HDMI you connect. Usually they are 1,2,3 and so on. Then this display will appear in the monitors. And already further you either duplicate screens or expand.
